1-Octene Hydroformylation Using Supported Amorphous Co-B Catalysts
摘要：
Co-B catalysts supported on ZrO2(prepared by alcogel nitrogen thermo-treatment method),carbon nanotubes(CNTs),and mesoporous SBA-15 as supports were prepared by chemical reduction method and characterized by X-ray diffraction(XRD),nitrogen physisorption,transmission electron microscopy(TEM),inductively coupled plasma-atomic emission spectrometry(ICP-AES) and X-ray photoelectron spectroscopy(XPS).Hydroformylation of 1-octene was used as a probe reaction to investigate the catalytic performance and stability of the catalysts in recycles.The as-prepared Co-B catalysts showed amorphous characteristics and the support structures were unchanged.The reaction results reveal that the catalytic activities of Co-B/CNTs,Co-B/ZrO2 and Co-B/SBA-15 in the hydroformylation of 1-octene were comparatively high.However,the catalytic activities decreased upon recycling.Nevertheless,the Co-B/ CNTs and Co-B/SBA-15 were relatively stable compared with Co-B/ZrO2.
